FOUNTAIN-PEN.

Specification forming part of Letters Patent No. 40.l35.datedSeptember'29, 1663.

- To all whom it may concern..-

Be it known that I, JOSEPH WELLER, of in the county of Fayette and Stateof Ohio, have invented a new and Improved Fountain-Pen; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being bad to the accompanying drawings, making partof this specification, in which- Figure 1 represents a side elevation ofmy invention. Fig. 2 represents a longitudinal central section of thesame.

Similar letters of reference indicate corresponding parts in bothfigures of the drawlugs.

The nature of my invention consists in a novel contrivance in afountain-pen, whereby the penman or user of the pen is enabled to supplythe nib with. fluid according as it is needed for either a fine orcoarse handwriting without lifting his hand from the paper, and also toprevent the pen being surcharged with fluid when in use or not, all aswill be hereinafter fully explained.

To enable others skilled in the art to which my invention appertains tounderstand the same, I will proceed to describe its construction andoperation.

A represents a tubular case, which may be made of sheet metal, silver,gold, or of any other suitable material. This case constitutes both thefountain and holder of the pen, and itis provided on the inside andlower end with a screw-thread to receive the screwthreaded end of thetube a, through which the fluid passes from the fountain to the pen. Thetube a is furnished immediately behind the screw-thread on its upper endwith a square shoulder, which,'when the two tubes A and a are unitedtogether, comes in close contact with the lower end of the tube A, andforms a tight joint, thus preventing any escape of fluid other than atthe. lower and discharging end of the tube a. The aperture which extendsthrough the tube a, at its lower end, opens out at one side of the tube,and at its upper end is countersunk to receive a shoulder, b, ofcorresponding form onthe central rod, B. This rod'is made of metal,andextends through a small aperture in the top of the tubular case,where it is provided with a fixed collar, n, and plug '5, and connectedby a pivot with one end of a rocking lever, O. The

plug '5 is simply a tapering rod, which, when in its lower position,enters and closes an airvent in the top of (the fluid-fountain.- portionof the rod B which extends below the shoulder b tapers gradually to apoint. p The lever O and upper portion of the central rod, B, areiucascd in a tubular cap, 0, which is screwed on the outside and upperend of the tubular case A. The cap cis provided on the inside with a.partition having two apertures formed in it-one for the central rod,B,to work through, and the other for a rod, D, which extends down on theoutside of the tubular case and serves as a medium through which theconical shoulder or stopper b and plug 43 are simultaneously raised toopen their respective apertures when it is desired to charge the penwith fluid. The rod D passes up on the inside of.the,cap c, and connectswith oneend of the rockiuglever O, the central rod being connected tothe other. The rocking lever 0 moves on a. fulcrum, e, which issupported atits ends in the sides of the cap a. A helical spring, E,interposed between the partition and upper side of a fixed collar, n, onthe central rod, B, acting through the rod B, forces the conicalshoulder or stopper 1) into the countersink in the tube a, andat thesame time by means of the plug [closes the air 'ent, and thus preventsthe escape of fluid when pressure is not being applied to the rod. Therod D. terminates at bottom in a foot, f, which stands at right angleswith the rod, and it (the rod) is kept in place on the tubular case by aferrule, 9, through a slot, in which it is allowed a free upand-downmovement. The pen is fastened to the tube by a ferrule, 71, as clearlyshown in Fig. 1

In writing with my improved fountainpen the second finger of the hand inwhich the pen is upon the foot of the rod. A slight pressure thenapplied to this foot with the second finger will raise the plug 6 so asto open the vent, and thus admit air into the fountain, andsimultaneously therewith raise the stopper 1) a suflicient distance toallow the fluid to pass into the countersink of the tube a, whence it isconducted by the tapering rod to thepen. The moment the foot is relievedThat held should be allowed to restof pressure the helical springreturns the stopper to the countersink and the plug to the vent, andthus stops the further flow of i fluid. I

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- Y 1. The central rod, B, provided with aconienl shoulder or stopper, 'b,' adapted tofit a countersink in theconverging tube a, in combination with the rocking lever 0,. rod D, and

helical spring E, when arranged to operate in the manner described.

parts, the plug 2', attached to the rod 13, and servingto open and closean air-ventage in the fountain, in the-manner and for the purposedescribed.
